| Highest Efficiency 1-Sun Solar Cell Posted: 24 May 2022 02:12 PM PDT Researchers have created a solar cell with a record 39.5% efficiency under 1-sun global illumination. This is believed to be the highest efficiency solar cell of any type, measured using standard 1-sun conditions. |
| A good defect? Researchers discover helicoidal screw dislocations in layered polymers Posted: 24 May 2022 01:36 PM PDT Researchers recently discovered a helicoidal-shaped defect in layered polymers, uncovering how solvents can diffuse through layers and produce color changes. |
| Experts forecast the wind plant of the future to be taller and more economical Posted: 24 May 2022 01:36 PM PDT Anticipating key features of wind plants a decade or more ahead of their installation can inform today's investment, research, and energy system planning decisions. Researchers elicited opinions from more than 140 of the world's leading experts about their expectations of future wind plant design in 2035. |
| Traveling wave of light sparks simple liquid crystal microposts to perform complex dance Posted: 24 May 2022 09:48 AM PDT Mastering control over the dynamic interplay among optical, chemical and mechanical behavior in single-material, liquid crystalline elastomers, results in microposts that combine bending, twisting and turning into complex dances. The advancement could contribute toward further development of soft robotics and other devices. |
| Emulating impossible 'unipolar' laser pulses paves the way for processing quantum information Posted: 24 May 2022 09:48 AM PDT A laser pulse that sidesteps the inherent symmetry of light waves could manipulate quantum information, potentially bringing us closer to room temperature quantum computing. |
| Developing next-generation superconducting cables Posted: 24 May 2022 09:46 AM PDT Researchers have demonstrated a new, ready-to-use superconducting cable system that uses helium gas for crucial cooling. |
| Scientists use quantum computers to simulate quantum materials Posted: 24 May 2022 09:46 AM PDT Researchers have used quantum computers to simulate spin defects, an important material property for the next generation of quantum computers. |
| Secret to treating 'Achilles' heel' of alternatives to silicon solar panels revealed Posted: 24 May 2022 08:07 AM PDT A team of researchers has found that the tiny defects which limit the efficiency of perovskites -- cheaper alternative materials for solar cells -- are also responsible for structural changes in the material that lead to degradation. |
| Scientists make plastic more degradable under UV light Posted: 24 May 2022 08:06 AM PDT Scientists found that incorporating sugar units into polymers makes them more degradable when exposed to UV light. |
| Significant energy savings using neuromorphic hardware Posted: 24 May 2022 07:06 AM PDT New research illustrates neuromorphic technology is up to sixteen times more energy-efficient for large deep learning networks than other AI systems. |
| Researchers develop algorithm to divvy up tasks for human-robot teams Posted: 24 May 2022 07:06 AM PDT Researchers have developed an algorithmic planner that helps delegate tasks to humans and robots. The planner, 'Act, Delegate or Learn' (ADL), considers a list of tasks and decides how best to assign them. The researchers asked three questions: When should a robot act to complete a task? When should a task be delegated to a human? And when should a robot learn a new task? |
